Patent ES-377083-A1 (ES)
Title: Transistor deflection circuits utilizing a class b, push-pull output stage
IPC: H04N3/16
Filed: 1970-03-03
Abstract: Transistorized vertical deflection circuit employs a multi-stage deflection wave amplifier including an output stage of a Class B, push-pull, complementary-symmetry type, with vertical yoke windings driven by output stage emitters. Ground return for vertical yoke windings is effected via path including electrolytic capacitor and current sampling resistor, with the capacitor blocking the flow through the yoke windings of direct current from the output stage. Deflection circuit employs Miller Integrator approach to sawtooth wave generation, developing sawtooth wave across a second capacitor included in a negative feedback path looped about the multi-stage deflection amplifier, the feedback voltage being derived from the current sampling resistor. Feedback use enables employment of relatively low-valued electrolytic capacitor for the D.C. blocking function without introducing undesired distortion of deflection current waveform. Vertical rate parabolic voltage developed across low-valued electrolytic capacitor is of adequate magnitude to serve as input waveform for vertical dynamic convergence circuits. In one embodiment, electrolytic capacitor serves as parabola source for additional feedback to Miller Integrator input in order to effect S-shaping of deflection wave.
Patent ES-381864-A1 (ES)
Title: Electrohydraulic hoist with mechanical backstop
IPC: F15B21/08
Filed: 1970-06-20
Abstract: A hoisting system, particularly for automotive vehicles, includes a single command lever (17) coupled with a three-position rotary distributing valve (16) and a two-position slide valve (13), the former serving to select one of three modes of operation ("up," "down" or "lock") whereas the latter responds to a shifting of the lever between an "off" and an "on" position. A hydraulic pump (7) works into a high-pressure line with a first branch leading to a hoisting cylinder (1) for elevating the load and with a second branch traversing the two valves in series, this latter branch having an outlet terminating at a set of latching cylinders (5) whose pistons bear upon spring-loaded detents (4) for arresting the load at a selected level of elevation in the "lock" position of the rotary distributor. The connection between the command lever and the slide valve includes a lost-motion coupling (17', 18) whereby in an intermediate shifting position, in which the lever is stopped in the "up" position of the distributor, the slide valve remains closed while an electric switch (25) is actuated to start the pump motor (6) which operates until the lever is restored or the motor circuit is broken by a limit switch (24) tripped at the top of the hoisting stroke. Another switch (29) is closed momentarily upon passage of the rotary distributor into or out of its "lock" position to establish an alternate energizing circuit for the pump motor which raises the load to release the detents (4) if engaged, this alternate circuit including a further switch (28) for stopping the pump motor after the load has risen a short distance above its locking level.

Title: Process for uranium separation and preparation of UO{HD 4{B .2NH{HD 3{B .2HF
IPC: C01G43/00
Filed: 1973-11-06
Abstract: A process for treating the aqueous effluents that are produced in converting gaseous UF6 (uranium hexafluoride) into solid UO2 (uranium dioxide) by way of an intermediate (NH4)4 UO2 (CO3) 3 ("AUC" Compound) is disclosed. These effluents, which contain large amounts of NH 4<+> (ammonium), CO3<--> (carbonate), F<-> (fluoride), and a small amount of U (uranium), are mixed with H2SO4 (sulfuric acid) in order to expel CO2 (carbon dioxide) and thereby reduce the carbonate concentration. The uranium is precipitated through treatment with H2O2 (hydrogen peroxide) and the fluoride is easily recovered in the form of CaF2 (calcium fluoride) by contacting the process liquid with CaO (calcium oxide). The presence of SO4<--> (sulfate) in the process liquid during CaO contacting seems to prevent the development of a difficult-to-filter colloid. The process also provides for NH3 (ammonia) recovery and recycling. Liquids discharged from the process, moreover, are essentially free of environmental pollutants. The waste treatment products, i.e. CO2, NH3, and U are economically recovered and recycled back into the UF6->UO2 conversion process. The process, moreover, recovers the uranium as a precipitate in the second stage. This precipitate is a new inorganic chemical compound UO4.2NH3.2HF [uranyl peroxide-2-ammonia-2- (hydrogen fluoride)].

Patent ES-457878-A1 (ES)
Title: Method of preparing inorganic monomeric and polymeric complexes and products so produced
IPC: C01B21/092
Filed: 1977-04-15
Abstract: Novel water soluble, inorganic complexes are obtained by reacting, in the presence of aqueous ammonia, at least one non-alkaline metal selected from Groups I-VIII of the Periodic Table with an alkali metal hydroxide. An excess of the non-alkaline metal or metals is introduced into a reaction vessel, preferably already containing the aqueous ammonia, and the alkali metal hydroxide is thereafter incrementally added in such manner as to create localized areas of high concentration and pH approaching a value of 14. The hydrooxide in these areas of high concentration, in combination with reactive NH2 groups provided by the aqueous ammonia, causes erosion of the non-alkaline metal, the formation of non-alkaline metal ions and the production of a monomeric, metal amide complex. The reaction parameters are maintained such that the rate of addition of alkali metal hydroxide is sufficient to suppress the expulsion from the system of ammonia gas while at the same time producing an overall endothermic reaction in which the ions of the alkali metal, the non-alkaline metal and the NH2 groups react to produce an inorganic complex. If the endothermic reaction is maintained and sufficient excess non-alkaline metal is present in the aqueous medium, after a period of time the reaction will enter an exothermic phase, producing an inorganic polymeric complex which remains soluble in water throughout a substantial molecular weight range.
